OPERATION

As air under pressure enters either end of the double

check valve (inlet port), the moving shuttle responds to the

pressure and seals the opposite port—assuming it is at a

lower pressure level than the other. The air ow continues

out the delivery port of the double check valve. The position

of the shuttle will reverse if the pressure levels are reversed.

Double check valves are designed so that the shuttle can

never impede the backow of air in the exhaust mode.

Figure 2 (see page 2) illustrates a typical double check

valve used to control a given device—such as trailer

brakes—from either of the two control sources.

DESCRIPTION

The Bendix

DC-4

double check valve is used in

an air brake system to direct a flow of air into a

common line from either of two sources, whichever is

at the higher pressure. The valves may be used for

directing air ow for specic functions or to select the

higher pressure of either of two sources of air as a

supply source.

Bendix manufactures two double check valves; one is

mounted in the air line without being secured to the vehicle

frame, and the other contains a mounting tab to secure

it to the vehicle frame or chassis. Although the valves

are somewhat different physically, the same function is

performed by each type.
